[flexcoders] Trouble with Combobox within a dynamically loaded swf
When I load a swf dynamically within another swf, there is a combobox near the bottom edge of the inner swf. When I click on it, the dropdown extends downward beyond the border of the inner swf, and is therefore mostly obscured. How can I make it so that the dropdown will extend upward? In a normal swf, if a combobox is near the bottom, the dropdown list will detect the stage border and extend upward instead. It seems like the combobox is not able to detect the loader's border. Is there a workaround if this is the case? Thanks!
Re: [flexcoders] Tree does not show scrollbar after inserting items
Thanks for the feedback guys! We are still on SDK 3.0 (that's what our project is currently based on and probably not going to change for this release in fear of other regression). But it's certainly good to know that this issue has been addressed in newer Flex. I will also give refresh collection a try.

[flexcoders] Tree does not show scrollbar after inserting items
After some googling, this seems to be an existing issue with Tree refreshes and I haven't been able to find a good workaround. The issue can be repro'ed at one of Adobe's quickstart demo page: http://www.adobe.com/devnet/flex/quickstart/working_with_tree/ Go to the last example, and expand all nodes in the tree on the left. Height doesn't exceed the container, so no scrollbar. Now drag elements from the right to the tree to insert them. When the height of tree extends beyond the container, no v-scrollbar is shown. But a scrollbar is shown after you collapse/expand the tree. Invalidating the tree's list/properties/displaylist didn't seem to cause a refresh. The underlying collection still returns old length when Tree processes configureScrollBars(). Can anyone suggest a good workaround? (aside from reassigning dataProvider, since that's too expensive for me.) A couple of old flexcoder threads also talks about this problem: http://tech.groups.yahoo.com/group/flexcoders/message/46541 http://tech.groups.yahoo.com/group/flexcoders/message/37627 Thanks!
[flexcoders] Debugging in Flex Builder crashes IE, Firefox, Safari...
Hi, Just about 2 weeks ago, I suddenly started getting a lot of crashes when trying to debug our app under Flex Builder (standalone). The crashes happen as soon as our app is loaded and it crashes IE7, FF3, Safari w/o any prior warning or exception. The crash is only happens when I try to run debug, never release. But about 1 in 3 debug sessions succeed without crash (with no code change in between whatsoever)... Thought it was caused by Flash 10 debug player, but installing v9 debug player didn't help. Googling reveals that OutofMem crashes Flash 10 player w/o warning, but this doesn't seem to be a Mem issue for me. Is anyone else experiencing this? -dave

[flexcoders] Is it possible to query Flash Player attributes e.g. "allowFullScreen"?
I couldn't find a way to check if "allowFullScreen" is set to true from within my Flex app. Is this possible at all? And to generalize, is it possible to query the other Flash settings that are set via or tag in the html, such as "wmode", etc?

[flexcoders] Re: Is there a way to detect mouse button state without tracking events?
Thanks for the suggestion. The problem is that when wmode=transparent on FF, if mouse button is already down (dragging scrollbar), and I exit the stage, MOUSE_LEAVE is not fired (or was eaten by a framework handler somewhere). But if mouse button is UP, then I do see a MOUSE_LEAVE event, but that doesn't help me. Problem is that the mouseUP is never processed when I'm outside the stage, so on re-entry, buttonDown is always true when it shouldn't be... --- In flexcoders@yahoogroups.com, "sunild99" wrote: > > Hi, > > You can use Event.MOUSE_LEAVE to detect when mouse has left the stage. > > You can listen for MouseEvent.MOUSE_MOVE if you need to know when the mouse > is back. > > Can you listen for MOUSE_LEAVE and dispatch your own MOUSE_UP event to stop > the list from scrolling? > > Sunil > > > --- In flexcoders@yahoogroups.com, Dave Kong wrote: > > > > This is a very urgent issue for us. =( Any help is deeply appreciated! > > > > On Thu, Mar 5, 2009 at 5:14 PM, Dave Kong wrote: > > > > > I need to find out at this particular moment, if the mouse button is up > > > or down. > > > > > > Trying to work around the issue with wmode=transparent in FF.

[flexcoders] Is there a way to detect mouse button state without tracking events?
I need to find out at this particular moment, if the mouse button is up or down. Trying to work around the issue with wmode=transparent in FF. If I scroll a list, and drags cursor outside of the player and then releases the button. That mouseUp event is never captured by Flash Player, so when I move mouse cursor back, buttonDown is always true for all mouse events. So I need a workaround on moues re-entry to detect if button is truly down, if not, call the scrollThumb's releaseButton function so it won't keep on scrolling. Thanks!
[flexcoders] Does the [SWF] meta tag really support widthPercect and heightPercent attribute?
link here http://www.actionscript.org/forums/showthread.php3?p=834470 seems to suggest that in addition to pixel width, I can specify percent value (similar to how I do it in html flash wrapper). But I can't get it to work. Is it really supported? [SWF(widthPercent="100", heightPercent="100")] Background: The reason I need it is to force a nested swf's size to match its parent container (loader?) width/height, so that the preloader is shown centered with respect to the parent application. Right now, while loading, the nested swf seems to be at a size of 500x325 (not sure where that value came from). And it is not center aligned wrt the parent. And I end up with a preloader that is off center. Any suggestions?
[flexcoders] Scrollbar in nested swf losing mouse event.
Hi every! Would really appreciate some help on this issue. It has been driving me nuts. So I have a nested swf loaded via the loader. In contains a List. When I mouseDown on the scrollbar inside that list, I can drag it as usual. But when I hold down the mouse key and move the pointer outside of the nested swf, but still inside the parent Flex app, the scrollbar no longer responds to any mouse movement. (The parent app does get mouse events.) Now, if I continue to hold the mouse button and move it out side of the entire browser, the scrollbar in nested swf once again gets the mouse drag events. If I release the mouse button while inside the parent app, and move the mouse pointer back into the nested swf, scrollbar will now respond to moues movement, as if the button is still in DOWN state. I'm guessing all mouse events are captured and "eaten" by the parent app while the pointer is outside of the nested swf, but still inside the browser. Is there any way I can continue to pass the mouse events into the nested swf even if I'm in the parent app? (just like how nested swf continue to get the moues event when I'm completely outside the browser). Once again, any help will be greatly appreciated! Thanks! -dave

Re: [flexcoders] Looking for what this[iscalled]
If you define lung as a public field of the class Whale, then it is no

believe those objects created at runtime via abc.xyz or abc["xyz"] has any
type associated with them, assuming xyz is not already declared as a field

Re: [flexcoders] Re: How to get an object to delete itself?
Why bother manually removing the reference to the timer's listeners? Assmuing only the timer has reference to those listeners, once the timer is deemed to be GC'ed (which will happen when its containing uic gets GC'ed after it's removed from parent), the listeners will also be GC'ed (since they can no longer be traversed from the root reference.) If the timer is not the sole reference to those listeners, then you dont want to GC them anyway.

Isn't "height" the "dynamic property" of another "dynamic property" this["something"] (which is equivalent to this.something)? the fact that you use [] syntax to access the property this.something is just a syntactical shorthand and sometimes a workaround: you can't define this.return (since return is a keyword), but you can do this["return"].

[flexcoders] How to convert an e4x XML object into an AS object?
I know SimpleXMLDecoder can decode a legacy XMLNode to an object and make good guesses at basic types such as string vs. int. But if I have the new e4x XML object, how do I easily convert that to objects? Or convert from E4X to XMLNode?
[flexcoders] Two difficult problems regarding synchronization of RPC in Flash
Problem 1: How can I make sure multiple asynch remote method calls do
not end up canceling each other?
Consider this pseudo code:
onButtonClick()
{
doStuff();
requestSoapData.addEventListener(..., handleSoapResult);
requestSoapData.send();
}
handleSoapResult()
{
doMoreStuff();
requestSoapData.removeEventListener(..., handleSoapResult);
// remove handler so this handler doesn't get called again when some
other control fires requestSoapData.
}
I add the listener before the call and remove after processing the
result, so that there will be no side-effect if another function calls
the same remote method. This was a pattern suggested to me previously
which I find is better than registering listeners permanently.
Now the problem is that since remote calls are asynchronous in nature,
how can I prevent the first result from coming back and removing the
listener BEFORE the second (or any subsequent) calls from invoking the
correct listener? Or am I somehow guaranteed that listeners will not
be removed until a pending remote call returns?
If this is not the correct pattern, then can anyone suggest a better
way of making sure each call to the *same* remote method invokes the
correct listener upon return w/o any side-effects from each other?
The single threaded nature of Flash Player that forces the asynch I/O
pattern leads me to my 2nd problem.
Problem 2: Is there an easy way to synchronize a string of network
calls at all?
I'm attempting to write a test script to test both my Flash frontend
and server backend. However, in order to run a series of tests, I need
to wait for the result from each previous remote call to come back
before invoking the next one.
One proven, but tedious way, is to have a string of listeners that
registers the next listener, then kicks off the next remote call. But
this just doesn't seem like good programming. The ugliness is next to
using nested if statements where a switch would do.
Can anyone suggest a better way of synchronizing remote calls for
testing purposes? Or is this just impossible due to Flash architecture?
Thanks!

honor the headers for me! Here's how to do it:
1) You must have the WS side of your app include the header info
directly in its WSDL, such as:
http://xyz.com/ListUsers"; style="document"/>
2) When you re-generate the code in Flex, it will then honor the
tag (along with the type definition for "SessionHeader"
at the beginning of the WSDL).
You will see new method generated on the XYZService class, such as
"addYOURWSMETHODNAME_header(header:YOURHEADERTYPE)". You call this
method to add the header you defined to the corresponding method, so
that every subsequent call will include the header.
(Note that the generated BaseService class actually includes header as
part of the WS call signature, but the generated top-level Service
class does not require header to be passed in the actual WS method
call each time. I think that's a good approach, since usually you use
headers for stuff like Session key which doesn't change often)
3) So how do you include the tag in WSDL? That depends
on your Back End. I'm currently using .Net, so I needed to add a
[SoapHeader] Attribute to the [WebMethods] that I want to include a
header. See MSDN doc here:
http://msdn2.microsoft.com/en-us/library/system.web.services.protocols.soapheader.aspx
Hope this helps!

[flexcoders] How to add SOAP header to Flex generated webservice code?
I have used the code generator in Flex and it was fairly smooth. All the web methods from the WSDL were corrected generated and call/result pairs come in bug-free. However, I can't figure out how to add some SOAP headers to the service so that every call can contain my headers. Does anyone have experience with this? I really do like the generator and do not want to manually write my service code. (There are too many web methods). I see a BaseXYZService which extends from AbstractWebService, however, calling its addHeader method succeeds, but no headers were included in the actual SOAP message. I noticed that the generated code uses WSDLOperation and other WSDLxxx objects, which probably does not honor AbstractWebService.headers array. (I assume those WSDLxxx are used by Apache Axis 2, can anyone point me to the source?) Any help to add headers to the Flex generated webservice code is GREATLY APPRECIATED!
[flexcoders] Generated Webservice code does not respect custom headers
I used Flex Builder to import webservice from a .net backup. The
generated code contained a _BaseGaiaService class that extends the
AbstractWebService and implements most of the actual operations. I can
get to that from the facade class GaiaService.getWebService() method.
I then wrote some test code to add headers like so:
var svc:BaseGaiaService = App.service.getWebService();
var q1:QName = new QName("http://abcd.com";, "Header1");
var header1:SOAPHeader = new SOAPHeader(q1, {string:"bologna",int:"123"});
var header2:SOAPHeader = new SOAPHeader(q1, {string:"salami",int:"321"});
svc.addHeader(header1);
svc.addHeader(header2);
svc.addSimpleHeader("Header3", "http://abcd.org";, "sausage", "222");
However, none of the subsequent calls contain any of these headers in
the SOAP envelope.
I've used this on my custom webservice class and headers can be added
successfully, so I suspect I'm not using the generated classes correctly.
Can anyone please help? Many thanks from a troubled Flex newbie.
[flexcoders] Re: Flex Feedback for the Future
I also *strongly* second the request for better printing capability on the client side. It's highly discouraging that after building an awesome Flex application, one finds out that you can't make decent printouts/reports and use them in a presentation. When people ask "hey, that is an awesome RIA/web app!" I can proudly say it's Flex and it's awesome.

[flexcoders] What are the available WSDL -> AS3/Flex code generators out there?
Hi, I've found Flextense to be a fairly good (free) tool translating my .net web service into as3 code that simplifies the tedious work of making up WebService result types on the Flex front end. There were 2 drawbacks: 1) it's not open source, so I can't tweak the code it generates to my liking. 2) it deleted my entire project folder in an attempt to generate code. (sure, it could be a user error from me for specifying my project folder as code output directory, but it should at least NOT nuke the output folder when encountering errors.) So, can anyone recommend other code generators out there? I know about WebOrb, but it's for direct remoting which I do not need at this point. I prefer to have my back end loosely coupled. Thanks!
